Human horse disease link probe in WA

A mysterious horse disease in Western Australia that may have been passed on to people is in no way related to the Hendra virus, government officials say.

The state's Department of Agriculture and Food is leading an investigation into the cause of lesions that were found in some horses near Pinjarra south of Perth three weeks ago.

The lesions are described as small raised lumps on the tongue and gums.

Since the discovery, the lesions have appeared in humans who have had contact with the horses, although they have been described as generally well.

The Department of Health is assisting with the investigation of the affected humans.

"At this stage, it is not clear if there is a relationship between the lesions reported in horses and people - and testing has not, as yet, revealed a cause for the lesions in either horses or people," a Department of Health spokesman said.

"Further testing will be conducted if indicated."

The spokesman said the lesions were in no way related to the Hendra virus, despite that being mentioned in a media report.

The Department of Health has advised people handling affected horses to take precautions including wearing disposable gloves and a face mask, and washing their hands well after contact.

"If they are concerned about their health they should consult a general practitioner," the spokesman said.
